The ruba or iiip hairs I claim: r 1. The combination with a splitautomobile-rim having side ianges; of a slide platencontacting with theinner periphery ofsaid rim and having its edges turned around 'said sideflanges, said slide late being' adapted to extend 4across the sp it ofthe rim to.l retain the rimends in alinement, said rlm ends and slideplate having reg1ster-- ing openings,. Vlocking studs insertible throughsaid openings to lock said rim ends and slide plate together, and flatsprings secured to the central portions of said rim ends and carryingsaid studs.

2. In a device of the class described, a transversely split demountablerim, and means for preventing separation of the rim ends while and afterapplying the rim t0 the wheel, comprising a slide plate contacting withthe innerperiphery of the rim and having its edges curved around the rimedges to prevent ldetachment of said plate except by endivisesliding,land coacting fastening means on said plate and the rim ends entirelyindependent of the Wheel felly and inaccessible for releasing when therim is secured upon the Wheel, said slide plate being movable entirelyonto one rim end when said fastening means are released.

3. T he combination with a split automobile rim having side flanges; ofa slide plate contacting with the inner periphery of said rim and havingits edges 'turned around said side flanges, said slide plate beingadapted toextend across the split of the rirn to re-l tain the rim endsin alinement, and means for connecting said slide plate and said rirnends, including registering openings therein, a stud for passage irstthrough therirn opening and then through the opening of said slideplate, and carrying means for .said stud positioned at the outerperiphery of the rim for Contact with the tube of a tire, wherebypressure of the tube against said carrying means will retain the latterin position to hold sai'd stud in said openinfrs. A y

tln testimony whereof i have hereunto set my hand. .l
